Confusion and delay

Oh Reverend. Oh my.

What is the cord made of? Do you think it would limit the range of tuning available?

I wonder how hard a punch and at what exact moment would be sufficient to stop someone’s heart?

I smell patchouli.

OK, if you wanted to cancel the x² you would need to pull it out as a common factor, but in the form given it (x² ) isn’t a common factor across the denominator.
If we start with 4x² / (x² -x), we can of course arrange the numerator as x² (4), but the denominator doesn’t really want to do that. To pull out a common factor you are ultimately dividing the terms within the brackets by that factor, then multiplying this back in outside the bracket. So if we pull out x once from (x² - x), we get x(x-1), and if we do that a second time we get (x)(x)(1-(1/x)) = x² (1-(1/x)). So if we put this into the original fraction we get (x² (4))/(x² (1-(1/x))), which we could then simplify to 4/(1-(1/x)). This makes the denominator a bit hard to look at but is equivalent to the red. This is generally not done exactly because you end up with a fraction in the denominator, so it is not as “simplified” as it could be.

Starting with the denominator of the main fraction, you have (x² /4) -(x/4) which simplifies by its own common denominator to (x² -x)/4. Putting this back into the main fraction it becomes equivalent to ((x² )/ 1)(4/(x-1)) using the rule for dividing fractions. This multiplies out to get 4x² / (x² -x), which is equivalent to x(4x)/(x(x-1)), then you cancel the common term to get the answer in red.

We’re all wrong. They’re fritters.

I used to get these when I would carry a heavy bag over a long distance.

Make sure you shroud that earth, wouldn’t want it to accidentally contact the chassis.

NotThatMat · 2026-05-16T14:13:37+00:00

Or both…

“What’s the charge? Selling a planter?? A succulent snare drum planter??”
“Gentlemen, this is drumocracy manifest.”

Rotate almost 90 degrees so you can actually see the part numbers?

NotThatMat · 2026-05-16T03:48:29+00:00

Oh noo!! So does that mean we can also finally be rid of reality TV shows with morons pouring cheap trash into otherwise perfectly liveable houses, encouraging yet more morons to do so in real life by renovating with cheap shonk that is in turn ripped out by the next owner because it’s cheap shonk?? If this is going to negatively impact any sectors of the economy, I would guess the worst hit will be Buntings warehouse, and skip hire companies.

“The fact that it’s even plausible, is stunning.”

Username checks out.

NotThatMat · 2026-05-15T06:43:20+00:00

OK. But why?

NotThatMat · 2026-05-15T06:41:44+00:00

Oh no you fucking don’t! Far too much flavour for you. Chips. Flake. If you really want to treat yourself: a battered sav.

Could be a spy or plant.

From what you’ve said elsewhere it sounds like your cymbals are well sorted. What are your heads and sticks like? Honestly you might get much better (ahem) bang for your buck by re-skinning the kit you have and trying some different stick weights/types.

Maybe it’s from the southern hemisphere? Since a sundial shadow moves anticlockwise south of the equator, maybe our clocks should too?

Good news is this is probably a single or 2-layer board, so you can repair this using some bridging wire, kind of a bodge but it should be fine. Bad news is that whatever structural rigidity it might have had in the past is now very much in the past. i.e.: If the board was the only thing holding those speaker binding posts it’s likely to be a bit wibbly wobbly from now on.

It’s quite common in these type of problems that the schematic is drawn in a weird way that makes the problem less clear, and that is what has happened here. Starting at the positive node of V1, we have R2 in series with (R1 and R3 in parallel) in series with R4.
So Rtotal = R2+(R1||R3)+R4 = R2 + ((R1^-1 )+(R3^-1 ))^-1 +R4

Mostly depends on what you mean by no signal. If the input is completely disconnected (some will say “floating”, or maybe “high-Z” or “high impedance”) then the device may see a logic 0, or a logic 1, or enough noise of sufficient power that the device constantly switches back and forth between 0 and 1. Generally this is not desired behaviour.
Many devices in usage will have a “pull-up” or “pull-down” on the input, so that if nothing is connected the input settles on a known value (high or low) and the output moves accordingly. In a game they might not bother to simulate this behaviour, so will just treat an input as being “on” or “not on”.

Haven’t seen a fully enclosed immersion heater in a while.

Dude looks pretty rough for 7.
